(2) Coralline Crag: Geol.: A division of the Suffolk Crag, distinguished superficially by its white color from the Red Crag, which constitutes the other division of the same series of beds. In the county where it has been best studied it is seldom more than twenty feet thick. It belongs to the Older Pliocene form a tion. The mollusca are very numerous, about sixty per cent. being recent species. The water in which it was deposited seems to have been deep and tran quil. +(3) Coralline deposits : Geol.: A name sometimes given to strata in large measure consisting of coral, and to presently existing reefs mainly the work of coral polypes.
